"We’ve interviewed three candidates [for the hitting coach position] and we may have a couple more," Gonzalez said. "We’ve got some good names."
We know that one of the candidates is former White Sox hitting coach Greg Walker, but the other two candidates interviewed so far remain a mystery. "We've got some good names" -- I take that to mean that perhaps some of the candidates interviewed may be established and well-known baseball people.
The vagueness with which he says "we may have some more" leads me to believe that they may have already found the guy they're looking for.
